+== Configuration Options
+
+The following table summarizes the configuration options available for the `pulsar-source` Kamelet:
+[width="100%",cols="2,^2,3,^2,^2,^3",options="header"]

+
+== Dependencies
+
+At runtime, the `pulsar-source` Kamelet relies upon the presence of the following dependencies:
+
+- camel:pulsar
+- camel:kamelet
+- camel:core 
+
+== Usage
+
+This section describes how you can use the `pulsar-source`.
+
+=== Knative Source
+
+You can use the `pulsar-source` Kamelet as a Knative source by binding it to a Knative object.
+
+.pulsar-source-binding.yaml
+[source,yaml]
+----
+apiVersion: camel.apache.org/v1alpha1
+kind: KameletBinding
+metadata:
+  name: pulsar-source-binding
+spec:
+  source:
+    ref:
+      kind: Kamelet
+      apiVersion: camel.apache.org/v1alpha1
+      name: pulsar-source
+    properties:
+      namespaceName: "The Pulsar Namespace Name"
+      serviceUrl: "The Service URL"
+      tenant: "The Tenant Name"
+      topic: "The Topic Name"
+      topicType: "The Topic Type"
+  sink:
+    ref:
+      kind: Channel
+      apiVersion: messaging.knative.dev/v1
+      name: mychannel
+
+----
+
+==== *Prerequisite*
+
+You have xref:{camel-k-version}@camel-k::installation/installation.adoc[Camel K installed] on the cluster.
+
+==== *Procedure for using the cluster CLI*
+
+. Save the `pulsar-source-binding.yaml` file to your local drive, and then edit it as needed for your configuration.
+
+. Run the source by using the following command:
++
+[source,shell]
+----
+kubectl apply -f pulsar-source-binding.yaml
+----
+
+==== *Procedure for using the Kamel CLI*
+
+Configure and run the source by using the following command:
+
+[source,shell]
+----
+kamel bind pulsar-source -p "source.namespaceName=The Pulsar Namespace Name" -p "source.serviceUrl=The Service URL" -p "source.tenant=The Tenant Name" -p "source.topic=The Topic Name" -p "source.topicType=The Topic Type" channel:mychannel
+----
+
+This command creates the KameletBinding in the current namespace on the cluster.
+
+=== Kafka Source
+
+You can use the `pulsar-source` Kamelet as a Kafka source by binding it to a Kafka topic.
+
+.pulsar-source-binding.yaml
+[source,yaml]
+----
+apiVersion: camel.apache.org/v1alpha1
+kind: KameletBinding
+metadata:
+  name: pulsar-source-binding
+spec:
+  source:
+    ref:
+      kind: Kamelet
+      apiVersion: camel.apache.org/v1alpha1
+      name: pulsar-source
+    properties:
+      namespaceName: "The Pulsar Namespace Name"
+      serviceUrl: "The Service URL"
+      tenant: "The Tenant Name"
+      topic: "The Topic Name"
+      topicType: "The Topic Type"
+  sink:
+    ref:
+      kind: KafkaTopic
+      apiVersion: kafka.strimzi.io/v1beta1
+      name: my-topic
+
+----
+
+==== *Prerequisites*
+
+* You've installed https://strimzi.io/[Strimzi].
+* You've created a topic named `my-topic` in the current namespace.
+* You have xref:{camel-k-version}@camel-k::installation/installation.adoc[Camel K installed] on the cluster.
+
+==== *Procedure for using the cluster CLI*
+
+. Save the `pulsar-source-binding.yaml` file to your local drive, and then edit it as needed for your configuration.
+
+. Run the source by using the following command:
++
+[source,shell]
+----
+kubectl apply -f pulsar-source-binding.yaml
+----
+
+==== *Procedure for using the Kamel CLI*
+
+Configure and run the source by using the following command:
+
+[source,shell]
+----
+kamel bind pulsar-source -p "source.namespaceName=The Pulsar Namespace Name" -p "source.serviceUrl=The Service URL" -p "source.tenant=The Tenant Name" -p "source.topic=The Topic Name" -p "source.topicType=The Topic Type" kafka.strimzi.io/v1beta1:KafkaTopic:my-topic
+----
+
+This command creates the KameletBinding in the current namespace on the cluster.
